Evaluación de la variabilidad en la calidad y cantidad del agua mediante Bioindicadores del Río Calope, en el área de influencia de la Hidroeléctrica Enermax S.A. del Cantón La Maná.

In the research project, the variability of the quality and quantity of water from the Calope River in the area of influence of the Enermax S.A hydroelectric was evaluated; that evaluation was carried out by through aquatic macroinvertebrates as bioindicators of water quality, 4 study points were established to do the study: points 1 and 2 at 200 m before the hydroelectric intake (San José River and Chuquiragua River respectively ); point 3, in the middle riverbed of the area of influence, and point 4, at 200 m after the discharge of the authorized flow, downstream from the machine house. It was also done gauges in five points, where only water flows were measured. Different biological indexes were applied with the obtained data; one of them was the Shannon rage, where it was verified that diversity decreases at high water flows; the ETP rage (Ephemeroptera, Trichoptera, and Plecoptera) was also applied which determined a quality of water from good to regular parameters in the rainy season, while in the dry season, it remains in good quality. As for the BMWP rage (Biological Monitoring Working Party), during the dry season, acceptable water quality was identified at all points; only in January is an uncertain water quality registered in point 1. The water flows measurement in the 5 points established allowed determining that the minimum flow is registered in October, considered as the dry season. Finally, the investigation was complemented with the analysis of physicochemical and microbiological parameters in two months (October and January), that allowed applying the NFS water quality rage (National Sanitation Foundation), determining a value corresponding to good quality water; Most of the analyzed parameters comply with current environmental regulations.
